846723d771 New rules for payment paths:
* Sanity check on newly created strands
* Better loop detection
* Better tests (test every combination of path element pairs)
* Disallow any root issuer (even for xrp)
* Disallow compount element typs in path
* Issue was not reset when currency was XRP
* Add amendment

122a5cdf89 Add V2 implementation of payments:
Add a new algorithm for finding the liquidity in a payment path. There
is still a reverse and forward pass, but the forward pass starts at the
limiting step rather than the payment source. This insures the limiting
step is completely consumed rather than potentially leaving a 'dust'
amount in the forward pass.

Each step in a payment is either a book step, a direct step (account to
account step), or an xrp endpoint. Each step in the existing
implementation is a triple, where each element in the triple is either
an account of a book, for a total of eight step types.

Since accounts are considered in pairs, rather than triples, transfer
fees are handled differently. In V1 of payments, in the payment path
A -> gw ->B, if A redeems to gw, and gw issues to B, a transfer fee is
changed. In the new code, a transfer fee is changed even if A issues to
gw.

100a76f0e8 Remove nested types SField::ref and SField::ptr...
* This silences a warning about a redundant cv-qualifier.
* This makes future coding mistakes about redundant
  cv-qualifiers much less likely.
* This makes the code easier to read.

99c2fac143 STVar: optimized storage for STObject (RIPD-825):
This introduces the STVar container, capable of holding any STBase-derived
class and implementing a "small string" optimization. STObject is changed
to store std::vector<STVar> instead of boost::ptr_vector<STBase>. This
eliminates a significant number of needless dynamic memory allocations and
deallocations during transaction processing when ledger entries are
deserialized. It comes at the expense of larger overall storage requirements
for STObject.

6283801981 Add non-unity build targets:
The SConstruct is modified to provide a new family of targets, ending with
the suffix ".nounity", which compile individual translation units instead of
some of the unity translation units ("classic" builds). Two modules updated
for this treatment are ripple/basics/ and ripple/protocol/, with plans to
update more in the future. A consequence is longer build times in some cases.
A benefit of classic builds is that missing includes can be identified
through compiler errors.
